Application med Ieren 24, 1917. Serial No. 157.161.

To all 'whom it may concern Be it known that I, Crrnrs'rran W. Hin- .iucnln'a citizen vof the United States of- America, and a resident ofthe city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Re frigerator Sho Cases, of which the followvingi` isa specification.

he primary object of this invention is to provide an improved arrangement ,of parts in a refrigerator show case so that a continuous cycle of air will be given to the-.foodstuit' chambers of the show case from Ithe ice container through the food-stuff chambers and returned to the ice container, from which the returned air will continuously pass through the ice container' and foodstuti' chambers.

Another object of this invention is to provide a refrigerator show case with longitudinally arranged guideways, as well asa longitudinally arranged ice container so that the circulated air currentswill be uniform intheir cycling travel, thereby preventing pocketing and stagnating the air.

@their and-further objects will appear in the specification and be specifically pointed out in the appended claims, reference being had to the accompanying drawings exempli- 'fyihg the invention, and in which,

Figure l is a plan view. of this improeid rigerator show case. L, Fig. 2 is a front elevation, partly in Section, taken on the line 11W-H of Fig. 1.

`Fig. 3 is a vertical section taken on the line lll-HI of Fig. 1.

Fig. i is a fragmentary horizontal section taken on the line lV--Ilr'of Fig'. 3.

Referring to the drawings, this improved refrigerator' show case comprises a front show glass 1, bottom 2, rear wall l and top wall 4, said top wall comprising 'a plurality of glass swinging doors 5, which provide access to the upper food-static chamber 6, and ice container covers 7 and8 that provide access tothe ice container 9.

Formed in the rear .Wall 3 are a plurality of swinging doors 10 which provide access to the lower 4food-stude chamber 11. Asshown more clearly in Figs. 3 and 4,- the ice 'container 9is located adjacent the rear wall 3 in the upper chamber 6, and entends longitudinally therein so that said ice container is ap roxiinately the ieng'th of said chamberY 6. lhe ice container 9 comprisesA a front side Wall 12 which is perforated, a rear wall which is composed of a perforated strip 13 which depends downwardly from the top wall l, and a solid portion 14.

, An inclined drip pan 15 is arranged beneath the bottom 16 of the ice container.

Dividing the. uppercharnber G from the lower chamber 11 is a horizontally and longitudinally arranged cold air deliector board and longitudinally arranged passageway 21 which kleads to the rear perforated portion 13.

In getting this improved refrigerator show ease ready for operation, the ice container 9 is filled preferably with cracked ice, so that when said ice is lying in mass formation in thev container, which is preferably kept filled, the ice will be in a porous condivrear Wall 3 of the show case, is a vertically tion, so that the air can rcirculate there- I through, and inasmuch as the cold air descends, the air contained in the ice container will fall to the bottom thereof and to- Ward the front perforated wall 12, andout of the lowerniost perforations in said wall, over the longitudinally arranged baille strip 22, thereby passing over andl around the food-stuffs mounted on the dellector bord or shelf 17, toward and through the longitudinally arranged passageway 20, into the lower foodstuff char-uber 11, and over and around the provisions arranged in the ottom 2, and as the temperature of the cold airk of the chamber 11 arises as the air travels toward the rear of said chamber 11, said warmer air will ascend, and upon. engaging the inclined` bottom of the drip pan 15, said warm air will be deflected toward and u-p the vertical passageway 21 toward the perforated strip 13, and upon engaging the inclined deflector board 23, will he forced through. the perforations of said perforated strip 13 and intoI the top of the ice container, said Warm air after being introduced into said ice container upon becoming chilled will descend and-be discharged through theperforations of 'the front wall 12 as afore related.

It is therefore seen that on account of the perforations of the front wall 12 of the con? taincr extending to a lower `plane than the perforations of the rear strip 13, that the cold air will always pass through said per- :Eorated wall 12, over the shelf 17, and'to ward and down the passageway 20, and after the cold air has entered the lower chamber l1, said air will be forced toward the rear of the show case on account of theV down draft, through said passageway ,20, at

which point said cold air will tend to become warmer, thereby arising and being deflected toward the vertical passageway '21 on account of engagement with the incline bottom of the drlp pan 15 which is incl-ined' upwardly toward said passageway 21.' ,Furthermore, the ice container being lon itudi nally arranged and lextending the full" ength pf the show case, andy the passageways 20 and 21 being of the same length, there will be a uniform current-of air ltraveling and making a complete cycle through the front n wall 12 of the ice container over the full length of the'shelf 17 and incidentally oyer the full/,length of the bottom 2, in which all of the a'1r contained'in the upper and lower chambers will be forced to continuall low or travel, thereby eliminating they pocieting of any air bodies, in which `the continual flowing cold air passing over the food-stuffs vof the upper and lower chambers will keep said foodstus fresh and in a salable condllOIl.' v

In an improved refrigerator show case of this character on account of the front wall being transparent as well as the top wall being provided with the glass doors 5, the. clerk behind the show case when waiting on y directions oik a customer through the glass f -doors as the customer'indicates or points against the transparent front' wall.

Whatl claim is: f 1. A` refrigerator show case having transparent front'and top Walls, -a horizontally arranged shelf having a solid surface dividing said case into a pair of chambers arranged vone above another, lan ice container having openin formed in opposing walls thereof locate to the rear of the upper chamber, a ypassageway formed adjacent the front wall 'of sald shelf leading' from the #supper toithe lower ,chamber and a second apassageway op ositely disposed from said first mentione passageway leald'rn from saidlower chamber to said ice container.

2. A refrigerator vshow casev having a thereof locate lin the upper one. of lsaid l chambersadjacent the rear wall thereof, the openings of one of-said wallslocated on a planelower than the openings of'said other wall of lsaid'containen a passageway leading from saidj upper chamber-to the Alower chamber located adjacent the fron .wall of the show case, and a second `positely disposed from said passageway opirst mentioned assageway leading from said lower chamer to thl side of sald ice container, in which the openings arearranged on a higher plane 'above the openings o1' said other wall of Asaid. ice container, said shelf providing 2 means forvdeflectin 'air currents from said container to said'. rstmentioned passage- CHRISTIAN w.
